Benefits of technology

The patent is about a way to treat eye conditions caused by problems with cone photoreceptors (the cells that help with color and vision) by injecting a special virus carrying a therapeutic gene into the eye. This method has shown promise in animals with experimentally induced cone dysfunction or death.

Problems solved by technology

However, these vectors must be administered by subretinal injection, a procedure that disrupts the structure of the retina and carries with it a risk of creating additional damage to retinal tissue that is often already damaged by the disorder being treated.

Background

[0174]New therapies are needed for the treatment of many cone photoreceptor associated disorders, including macular dystrophies such as cone-rod dystrophy, cone dystrophy, Stargardt macular dystrophy, and achromatopsia; color vision disorders such as protan, deutan, and tritan defects; and vision disorders of the central macula such as age-related macular degeneration, macular telangiectasia, retinitis pigmentosa, diabetic retinopathy, retinal vein occlusions, glaucoma, Sorsby's fundus dystrophy, adult vitelliform macular dystrophy, Best's disease, and X-linked retinoschisis. As these vision disorders are associated with a loss of function and / or viability of the cone photoreceptors, it is hypothesized that these disorders may be treatable by delivering a therapeutic gene to cone photoreceptors to rescue cone viability and function.

[0175]To that end, the polynucleotide cassette “pMNTC” was designed in which enhancer, promoter, 5′UTR, intron, Kozak, and polyadenylation sequ...

Abstract

Methods and compositions are provided for intravitreally delivering a polynucleotide to cone photoreceptors. Aspects of the methods include injecting a recombinant adeno-associated virus comprising a polynucleotide of interest into the vitreous of the eye. These methods and compositions find particular use in treating ocular disorders associated with cone dysfunction and / or death.
